FIELD OF THE INVENTION

This invention relates to novelty trading items and, more particularly,to novelty trading items for storing and communicating data toenthusiasts, hobbyists, and collectors.

BACKGROUND OF THE INVENTION

Over the years the trading card industry has developed as both a noveltyitem and a collectors item. As time goes by, the value of many of thesetrading cards which have printed indicia thereon has increased so thatthe trading card industry has grown significantly over the years andmany trading cards have substantially increased in value. As technologyhas changed, however, various types of trading cards and methods ofstoring and communicating data have been developed.

The concept of associating card devices which store and communicateinformation to a user with indicia or an image thereon has been knownfor many years. Examples of such devices can be seen in U.S. Pat. No.3,691,312 by Petersen titled "Tape Recording Apparatus And System HavingA Very Thin Cassette," U.S. Pat. No. 4,904,853 by Yokokawa titled"Dual-Function Information-Carrying Sheet Device," U.S. Pat. No.5,411,259 by Pearson et al. titled "Video Sports Game System UsingTrading Cards," and U.S. Pat. No. 5,433,035 by Bauer titled "TalkingEntertainment Card." These prior card devices, however, either usedolder methods of storing and communicating information such as cassettesor used integrated circuit technology. Accordingly, these prior methodscan be expensive and complex to manufacture even in large volumes andneither understood nor appreciated the benefits, capabilities, design,or construction of optical digital data storage devices, and moreparticularly optical compact discs. Only recently has the technology andconcepts related to the use of optical digital data storage devicesreally increased and been accepted in the market so that the relativeprice of optical digital data storage media has decreased dramatically.

Conventional compact discs, for example, are conventionally fabricatedin either 80 millimeter ("mm") or 120 mm sizes and are formed ofgenerally rigid plastic discs. As understood by those skilled in theart, the discs are often formed by the use of a mold-based replicationsystem using injection molding techniques. Each compact disc includes aseries of either circular or spiral data tracks which are illuminatedand read by a source of coherent light such as a laser. In producingthese compact discs, data is optically mastered from data files andpositive copies of the data are made. Die stampers are produced fromelectroplated shims, and discs are molded from the negative images onthe die stampers. The discs are then individually metalized, and alacquer coating is applied to each disc. The layer of rigid plasticpositioned between each data track and the source of coherent lightprovides structural rigidity, protects the data tracks, and alsofunctions as a single integral lens element to refract and focus thecoherent light beam onto a selected data track. A disc label is alsoprinted, and the disc inserted into a clam shell or other package forshipment to customers.

Recently, however, other thin film digital data storage medium andmethods of manufacturing digital data storage media have been developedincluding for use with trading cards. An example of this thin filmdigital data storage medium and related methods can be seen in U.S. Pat.No. 5,579,296 by Smith et al. titled "Optically Readable Thin FilmDigital Data Storage Medium." These recently developed trading cards,however, require extensive and new manufacturing investments, require aspecial adaptor to make the trading cards compatible with compact discplaying systems, and can be inhibited by marketing and manufacturingconstraints, including the additional special adaptor, which can makethis recently developed technology less commercially feasible.

SUMMARY OF THE INVENTION

With the foregoing in mind, the present invention provides a tradingcard optical compact disc and methods of using a compact disc which arereadily compatible with existing disc readers and relatively inexpensiveto manufacture. The present invention also advantageously provides atrading card optical compact disc and method of forming a trading cardthat stores and communicates trading card information to a user of adisc reader in a manner that is relatively easy to manufacture inconjunction with known optical compact disc manufacturing techniques andthereby does not require extensive additional molding and tooling costs.The present invention further provides a trading card optical compactdisc which does not require a separate special adapter for compatibilitywith existing disc readers.

More particularly, a trading card optical compact disc and method ofusing and forming the compact disc are provided which are compatiblewith a disc reader having a centrally located spindle and a seating ringfor supporting and rotating a compact disc positioned thereon. Thetrading card optical compact disc according to a first embodiment of thepresent invention preferably has at least a first plastic rectangularlayer having a width of about 2.5 inches and a length of about 3.5inches and having a pattern of digital data encoded thereon. A secondmetallic layer if formed on at least portions of the first plasticlayer, and a third protective layer is formed on at least the secondlayer for protecting the metallic layer. An indicia bearing fourth layeris formed on the third layer and has a generally planar upper surfacefor displaying indicia therefrom. An opening extends through the first,second, third, and fourth layers in a medial portion thereof. Tradingcard interface seating means is preferably integrally formed in at leastthe first layer for seating the trading card onto a loading tray of adisc reader so as to interface with only portions of the seating ringand not other portions of the seating ring of the disc reader and toread digital data stored thereon from the trading card optical compactdisc.

According to the present invention, the trading card seating means ispreferably provided by the at least a first plastic layer which has amajor elevational portion having a first predetermined height and aminor elevational portion having a second predetermined height. Themajor elevational portion has the encoded digital data thereon, and theminor elevational portion is preferably devoid of the encoded digitaldata. For alignment, balancing, and compatibility purposes, the majorelevational portion is advantageously formed in a medial portion of thetrading card and has first and second pairs of spaced-apart outer sideperipheries defining outer boundaries of the major elevational portion.Each of the first pair of space-apart outer side peripheries arcuatelyextend between each of the second pair of space-apart outer sideperipheries. Each of the second pair of space-apart outer sideperipheries extend generally linearly between each of the first pair ofspaced-apart outer peripheries. Each of the arcuately-extending firstpair of spaced-apart outer side peripheries of the major elevationalportion are centered about an axis extending through the medial openingand generally perpendicular to the linearly-extending second pair ofspace-apart outer side peripheries. The encoded digital data of themajor elevational portion of the first layer is formed within a circulardata zone and preferably does not cover, i.e., less than, the entiresurface area of the major elevational portion of the first layer. Thecircular data zone has a first inner circular periphery having a radiusof at least 0.6 inches and a second outer circular periphery having aradius of less than 1.25 inches. The circular data zone is preferablycapable of storing between 60-70 Megabytes of information or datatherein in some compact disc formats, e.g., audio or CD-ROM, or 450-500Megabytes in other compact disc formats, e.g., digital video. A firstnon-metallic zone surrounds and extends outwardly a predetermineddistance from the medial opening, and a second non-metallic zone extendsinwardly from the rectangular outer perimeter of the trading cardoptical compact disc a predetermined distance.

By the provision of the trading card interface seating means, thetrading card optical compact disc of the present inventionadvantageously allows a user thereof to readily position the disc into aconventional disc reader with any separate special attachments,adapters, or fasteners. The positioning of and construction of thetrading card interface seating means also enables the disc to balanceand rotate effectively within a conventional disc reader. By notrequiring a separate adapter, the trading card optical compact discadvantageously can be easier to use and, is some embodiments, easier andless expensive to manufacture.

A method of using a trading card optical compact disc to communicatedigitally encoded data to a user of an optical disc reader is alsoprovided according to the present invention. The method preferablyincludes positioning a trading card optical compact disc having anopening extending through a medial portion thereof onto a loading trayof a disc reader so that the compact disc interfacingly seats onto onlyportions of a seating ring and not other portions of the seating ring ofthe disc reader.

Additionally, methods of forming a trading card optical compact disc areprovided according to the present invention. A method preferablyincludes molding at least a first plastic rectangular layer having awidth of about 2.5 inches and a length of about 3.5 inches and having apattern of digital data encoded thereon. The at least a first plasticlayer preferably includes a major elevational portion having a firstpredetermined height and a minor elevational portion having a secondpredetermined height. The major elevational portion has the encodeddigital data thereon and the minor elevational portion is devoid of theencoded digital data.

Another method of forming a trading card optical disc preferablyincludes positioning a compact disc having a pattern of digital dataencoded thereon onto a medial portion of a surface of a trading cardhaving a width of about 2.5 inches and a length of about 3.5 inches, thecombination of the compact disc and the trading card having a majorelevational portion and a minor elevational portion so that the majorelevational portion interfacingly seats the combination onto a loadingtray of a disc reader so as to interface with only portions of theseating ring and not other portions of the seating ring of the discreader and to read digital data stored thereon from the trading cardoptical compact disc. The major elevational portion has the encodeddigital data thereon, and the minor elevational portion is preferablydevoid of the encoded digital data. The major elevational portion hasfirst and second pairs of spaced-apart outer side peripheries definingouter boundaries of the major elevational portion. Each of the firstpair of space-apart outer side peripheries arcuately extends betweeneach of the second pair of space-apart outer side peripheries. Each ofthe second pair of space-apart outer side peripheries extends generallylinearly between each of the first pair of spaced-apart outerperipheries.

Because the trading card optical compact disc and associated methodswere conceived and developed while keeping in mind the commercialviability and ease of manufacturing, the trading card optical compactdisc is preferably formed using conventional compact disc manufacturingtechniques. This, for example, advantageously allows training, tooling,and other associated manufacturing costs to be reduced andadvantageously provides incentives for manufacturers to more readilyaccept the technology for manufacturing purposes. In contrast to otherknown concepts, by providing incentives to make this technology readilymanufacturable by existing compact disc manufacturers, the presentinvention achieves a significant goal in reducing the overall price ofthe end product to ultimate purchasers.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

The present invention will now be described more fully hereinafter withreference to the accompanying drawings, in which preferred embodimentsof the invention are shown. This invention may, however, be embodied inmany different forms and should not be construed as limited to theembodiments set forth herein. Rather, these embodiments are provided sothat this disclosure will be thorough and complete, and will fullyconvey the scope of the invention to those skilled in the art. Likenumbers refer to like elements throughout, and prime and double primenotation are used to indicate similar elements in alternativeembodiments.

FIG. 1 illustrates a perspective view of a trading card optical compactdisc 20 according to an embodiment of the present invention. The tradingcard optical compact disc 20 is preferably compatible with a disc reader15 (see FIGS. 9-10) which includes a centrally located spindle S and aseating ring R of a loading tray T for supporting and rotating a compactdisc ("CD") positioned thereon. The trading card optical compact disc 20has at least a first plastic rectangular layer 21 having a width ofabout 2.5 inches and a length of about 3.5 inches and having a patternof digital data encoded thereon, i.e., pits and tracks as understood bythose skilled in the art. The plastic of the first layer 21 ispreferably a polycarbonate material or other optically transparentembossable plastic material as understood by those skilled in the art.

Various formats or data categories, including compact disc audio data,digital video disc ("DVD"), and/or compact disc read-only-memory ("ROM")data can be embossed into and stored on the first layer 21 by techniquesknown to those skilled in the art. For trading card applications (seeFIG. 1), for example, digital data including visual information ofphotographs, video, textual information such as a person's or team'sstatistics and biographies, historical information, music, narration,and other data can be stored and recalled at will be a user of a discreader 15. As understood by those skilled in the art, these trading cardapplications, for example, can include sports, music, entertainment,publishing, book, magazine, topical information, or various other typesand formats of trading cards.

A conventional compact disc reader 15, for example, can include aloading tray T having a centrally located spindle S and a seating ring Rfor supporting and rotating a compact disc having planar upper and lowersurfaces and embedded data tracks consisting of the encoded digitaldata. A compact disc reader 15 also has a digital data reading systemwhich includes a source of light positioned for generating a light beamto illuminate the data tracks. A light beam is reflected from the datatracks and is modulated by the encoded digital data. A digital readingsystem of the compact disc reader 15 receives and converts acorresponding electrical signal for processing the read data, e.g., by amicroprocessor-based decoding system.

Preferably, as illustrated in FIGS. 2A-2B, 3-5 and 8, a second metalliclayer 24 is formed on at least portions of the first plastic layer 21,e.g., portions of or the entire major elevational portion 22 of thefirst plastic layer (see FIGS. 2A and 4). The metallic layer 24preferably includes an aluminum material, such as conventionally usedwith forming optical compact discs, silver material, gold material, orother reflective metal material. The second layer 24 preferably providesa reflective surface for the light beam after it passes through thefirst optically transparent plastic layer 21 when attempting to read thedigitally encoded data from the disc 20. As illustrated in FIGS. 2B and5, for ease of manufacturing and aesthetic purposes, a second embodimentof the trading card 20' illustrates that the second layer 24' can alsoextend substantially the full length and width of the trading cardoptical compact disc 20'. The second embodiment also includes a firstlayer 21', a major elevational portion 22', the second layer 24', athird layer 26', a fourth indicia bearing layer 28', and a medialopening 32' extending therethrough (see also opening 32" of FIG. 8) asillustrated. In either the first or second embodiments of the tradingcard optical compact disc 20, 20', however, a non-metallic zone 23, 23'(see also 23" of FIG. 7) is preferably formed around the entireperipheries of the trading card optical compact disc 20, 20'.

Additionally, a third protective layer 26 is preferably formed on atleast the second layer 24 for protecting the metallic layer 24 such asfrom chipping, flaking, or other damage. The third layer 26 ispreferably a lacquer material or other thin hard coat material which isformed on the first and second layers 21, 24 to enhance the scratchresistance and provide other protection for these layers 21, 24. Afourth indicia bearing layer 28 is preferably formed on the third layer26 and has a generally planar upper surface for displaying indicia 29therefrom (see also indicia 29" of FIG. 6). The indicia 29 is preferablya photograph, sketch, textual information, or other images formed by inkor other material formed or positioned onto either the lacquer layer orformed by another material, e.g., paper or plastic, formed on or adheredto the lacquer layer 26. Also, for example, if the indicia bearing layeris a paper material adhered to the lacquer layer 26, then an adhesive ispreferably positioned therebetween. The thickness of the combination ofthe first, second, third, and fourth layers 21, 24, 26, 28 of the firstand second embodiments is preferably less than about 0.06 inches or 1.5mm.

As best shown in FIGS. 6-8, the thickness of the combination of thefirst, second, third, and fourth layers 21", 24", 26", 28" of the thirdembodiment of a trading card optical compact disc 20", e.g., a DVDformat, which preferably uses a digital video data format is alsopreferably less than about 0.06 inches or 1.5 mm. This embodiment, asunderstood by those skilled in the art, preferably has at least twoplastic layers 21a", 21b" each which are less than 0.03 inches or 0.75inches or which form a composite layer and defines a major elevationalportion 22" as illustrated in the other embodiments. These two plasticlayers 21a", 21b", however, are also preferably positioned prior to themetallic layer or second layer 24". These plastic layers 21a", 21b" arepreferably used for data encoding, focusing, and image enhancement,especially in the DVD format as understood by those skilled in the art,have smaller pits, and form two levels of digitally encoded data.

An opening 32 preferably extends through the first, second, third, andfourth layers 21, 24, 26, 28 in a medial portion thereof (see FIGS. 1-2Band 6-7). The trading card optical compact disc 20 preferably has aperforated opening cover 33 which preferably attaches along perforationlines to either the third or fourth layers 26, 28. The opening cover 33is preferably packaged and shipped with the trading card optical compactdisc 20 so that the purchaser or user of the card can detach or removethe opening cover 33 from the card 20 for positioning the card 20 ontothe spindle S of a disc reader 15. The opening 32 preferably has adiameter of about 0.6 inches, i.e., about 15 mm, and is primarily usedto mount the card 20 onto the spindle S of a disc reader 15.

As illustrated in FIGS. 2A-2B, 3-5, and 7-8, a trading card opticalcompact disc 20 of the present invention also preferably has tradingcard interface seating means 40, e.g., preferably provided by a tradingcard interface seat, integrally formed in at least the first layer 21for seating the trading card 20 onto a loading tray T of a disc reader15 so as to interface with only portions of the seating ring R and notother portions of the seating ring R of the disc reader 15 and to readdigital data stored thereon from the trading card optical compact disc20. The trading card seating means 40 preferably includes at least thefirst plastic layer having a major elevational portion 22 having a firstpredetermined height and a minor elevational portion 23 having a secondpredetermined height. The first predetermined height preferably is about0.05 inches. The major elevational portion 22 has the encoded digitaldata thereon, and the minor elevational portion 23 is preferably devoidof the encoded digital data. By the provision of the trading cardinterface seating means 40, the trading card optical compact disc 20therefore advantageously does not require a separate special adapter forcompatibility with existing disc readers. The positioning of andconstruction of the trading card interface seating means 40 also enablesthe disc 20 to balance and rotate effectively within a conventional discreader 15.

The major elevational portion 22 is formed in a medial portion of thetrading card 20 and has first and second pairs of spaced-apart outerside peripheries defining outer boundaries of the major elevationalportion 22. Each of the first pair of space-apart outer side peripheriesarcuately extend between each of the second pair of space-apart outerside peripheries. Each of the second pair of space-apart outer sideperipheries extend generally linearly between each of the first pair ofspaced-apart outer peripheries. Each of the arcuately-extending firstpair of spaced-apart outer side peripheries of the major elevationalportion 22 are centered about an axis A extending through the medialopening 32 and generally perpendicular to the linearly-extending secondpair of space-apart outer side peripheries 38 (see also 38' of FIG. 2Band 38" of FIG. 7). A radius extending from a medial portion of themedial opening 32 to each of the arcuately-extending first pair ofspaced-apart outer side peripheries of the major elevational portion 22is less than 1.6 inches.

As perhaps best illustrated in FIG. 2A, the encoded digital data of themajor elevational portion 22 of the first layer 21 is formed within acircular data zone 34 (see also 34' of FIGS. 2B and 5 and 34" of FIG. 7)and preferably does not cover, i.e., is less than, the entire surfacearea of the major elevational portion 22 of the first layer 21. Thecircular data zone 34 has a first inner circular periphery having aradius of at least 0.6 inches and a second outer circular peripheryhaving a radius of less than 1.25 inches. The circular data zone 34 ispreferably capable of storing between 60-70 Megabytes of digitalinformation or digital data therein in some formats, e.g., audio orCD-ROM and capable of storing between 450-500 Megabytes of digitalinformation in other formats, e.g., DVD. A first non-metallic zone 36(see also 36' of FIGS. 2B and 5 and 36" of FIG. 7) surrounds and extendsoutwardly a predetermined distance from the medial opening 32. A secondnon-metallic zone 38 extends inwardly from the rectangular outerperimeter of the trading card optical compact disc 20 a predetermineddistance. The first non-metallic zone 36 preferably includes a stackingring 37 (see also 37' of FIGS. 2B and 5 and 37" of FIG. 7) surroundingthe opening 32 for stacking another optical compact disc thereon such asused during mass production. It will be understood by those skilled inthe art, however, that the stacking ring 37 is not necessary in theconstruction of the trading card optical compact disc 20 according tothe present invention.

As illustrated in FIGS. 1-10, the present invention also advantageouslyprovides methods of using and methods of forming a trading card opticalcompact disc 20 according to the present invention. As perhaps bestillustrated in FIG. 9, a method of using a trading card optical compactdisc 20 to communicate digitally encoded data to a user of a disc reader15 preferably includes positioning a trading card optical compact disc20 having an opening 32 extending through a medial portion thereof ontoa spindle S of a disc reader 15. The compact disc 20 preferablyinterfacingly seats onto only portions of a seating ring R and not otherportions of the seating ring R of the disc reader 15. The trading cardoptical compact disc 20 can also be rotated so as to read digitallyencoded data therefrom (see, e.g., FIG. 10).

A method of forming a trading card optical compact disc 20 according tothe present invention preferably includes molding at least one plasticrectangular layer 21 having a width of about 2.5 inches and a length ofabout 3.5 inches and having a pattern of digital data encoded thereon.Prior to this molding step, however, and as understood by those skilledin the art, data for the disc 20 is optically, e.g., preferably by lasertechniques, mastered from data files or other software programs. Themaster is then electroplated with a metal material, e.g., silver, andprepped for replicating positive mold copies or shims. Die stampers areproduced from the electro-plated shims. The plastic layer 21 is thenformed by injection molding from a negative image on a die stamper.Alternatively, as understood by those skilled in the art, two plasticlayers 21a", 21b" can be formed as illustrated in FIG. 8 for DVDformats. The plastic layer 21 preferably includes a major elevationalportion 22 having a first predetermined height and a minor elevationalportion 23 having a second predetermined height. The major elevationalportion 22 preferably has the encoded digital data thereon, and theminor elevational portion 23 is preferably devoid of the encoded digitaldata. These major and minor elevational portions 21, 24 and thedigitally encoded data are preferably formatted and implemented in theoptical mastering step.

The major elevational portion 22 is preferably formed in a medialportion of the trading card optical compact disc 20 and has first andsecond pairs of spaced-apart outer side peripheries defining outerboundaries of the major elevational portion 22. Each of the first pairof space-apart outer side peripheries arcuately extend between each ofthe second pair of space-apart outer side peripheries. Each of thesecond pair of space-apart outer side peripheries extending generallylinearly between each of the first pair of spaced-apart outerperipheries. The encoded digital data of the major elevational portion22 of the plastic layer 21 is preferably formed within a circular datazone 34 and comprises less than the entire surface area of the majorelevational portion 22 of the plastic layer 21. The molding of theplastic layer 21 preferably includes molding an opening 34 extendingthrough a medial portion of the plastic layer 21.

The method can also include applying a metallic layer 24 on at leastportions of the plastic layer 21 and applying a third protective layer26 on at least the metallic layer 24 for particularly protecting themetal material of the metallic layer 24. The metallic layer 24, forexample, can be applied by metalizing the plastic layer 21 through ahigh speed spinning process or other metalizing processes known to thoseskilled in the art. The third layer 26 is preferably applied by pouringor spraying a curable liquid onto the second layer 24 in a controlledmanner. The method can further include applying an indicia bearing layer28 on the third layer 26. The indicia bearing layer 28 preferably has agenerally planar upper surface for displaying indicia 29 therefrom. Theformed disc 20 can then be packaged in a clam shell package, a custompackage, or other compact disc package as understood by those skilled inthe art. The present invention thereby advantageously provides a tradingcard optical compact disc 20 and method of forming a trading card thatstores and communicates trading card information to a user of a discreader 15 in a manner that is relatively easy to manufacture inconjunction with known optical compact disc manufacturing techniques,e.g., an in-line production process, and thereby does not requireextensive additional molding and tooling costs.

A method of forming a trading card optical compact disc 20 according toanother embodiment of the present invention includes positioning acompact disc having a pattern of digital data encoded thereon onto amedial portion of a surface of a trading card having a width of about2.5 inches and a length of about 3.5 inches. The combination of thecompact disc and the trading card preferably have a major elevationalportion and a minor elevational portion so that the major elevationalportion interfacingly seats the combination onto a loading tray T of adisc reader 15 so as to interface with only portions of the seating ringR and not other portions of the seating ring R of the disc reader 15 andto read digital data stored thereon from the trading card opticalcompact disc 20. The major elevational portion 22 has the encodeddigital data thereon and the minor elevational portion 23 is preferablydevoid of the encoded digital data. The major elevational portion 22 hasfirst and second pairs of spaced-apart outer side peripheries definingouter boundaries of the major elevational portion 22. Each of the firstpair of space-apart outer side peripheries arcuately extends betweeneach of the second pair of space-apart outer side peripheries. Each ofthe second pair of space-apart outer side peripheries extends generallylinearly between each of the first pair of spaced-apart outerperipheries. The major elevational portion 22 is formed in a medialportion of the trading card 20 and has first and second pairs ofspaced-apart outer side peripheries defining outer boundaries of themajor elevational portion 20. Each of the first pair of space-apartouter side peripheries arcuately extending from each of the second pairof space-apart outer side peripheries. Also, each of the second pair ofspace-apart outer side peripheries extending generally linearly fromeach of the first pair of spaced-apart outer peripheries. Thecombination preferably includes an opening 32 formed in a medial portionthereof. Each of the arcuately-extending first pair of spaced-apartouter side peripheries of the major elevational portion are centeredabout an axis extending through the medial opening 32 and generallyperpendicular to the linearly-extending second pair of space-apart outerside peripheries.
